No sw “mode”can change the minimum focal distance of a lens. That’s baked into the lens construction itself. Most macro modes simply crop the image (or do some digital zoom) anyway. So best thing is to make the photo then crop the image to your liking.
There is an advantage to this also as a “real” macro lens (when you get closer and closer) has a very limited DOF.
Here are a few examples (not taken it’s a S9 obviously, but with a phone none the less). I have a couple of shots of the flowers in my hand to give a idea of the real size. The “macro” photos are simply crops from a larger FOV.
